Enable Dynamic Access Control List (ACL) for the HTTP Application Layer Gateway (ALG)
Dynamic ACL option, which provides Distributed Denial of Service (DDoS) attack protection for the HTTP port, is an option that you must enable.
Confirm that the session manager is mapped to the
Oracle® Enterprise Session Border Controller.
Two ACL entires are required for each registered telephone, where one entry is used for SIP traffic and one is used for HTTP-ALG traffic.
Note:
Enabling dynamic access control for HTTP-ALG traffic reduces the number of available dynamic ACL entries on the session border controller, which may reduce the number of concurrent trusted endpoints that the system can support.
